如何使用Python将文件夹中的项目从远程服务器下载到本地目录？

import paramiko
import os

def download_folder(remote_path, local_path, hostname, username, password):
    # 创建SSH客户端
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    
    try:
        # 连接远程服务器
        client.connect(hostname=hostname, username=username, password=password)
        
        # 创建SFTP客户端
        sftp = client.open_sftp()
        
        # 递归下载文件夹
        download_recursive(sftp, remote_path, local_path)
        
        print("文件夹下载完成！")
    except Exception as e:
        print("下载文件夹时出现错误：", str(e))
    finally:
        # 关闭SFTP客户端和SSH客户端
        sftp.close()
        client.close()

def download_recursive(sftp, remote_path, local_path):
    # 获取远程文件夹中的文件和子文件夹
    files = sftp.listdir(remote_path)
    
    for file in files:
        remote_file = os.path.join(remote_path, file)
        local_file = os.path.join(local_path, file)
        
        if sftp.isfile(remote_file):
            # 如果是文件，则下载到本地目录
            sftp.get(remote_file, local_file)
        elif sftp.isdir(remote_file):
            # 如果是文件夹，则递归下载
            os.makedirs(local_file, exist_ok=True)
            download_recursive(sftp, remote_file, local_file)

# 设置远程服务器的连接信息
hostname = "远程服务器IP地址"
username = "用户名"
password = "密码"

# 设置远程文件夹路径和本地目录路径
remote_path = "/远程文件夹路径"
local_path = "/本地目录路径"

# 调用函数进行文件夹下载
download_folder(remote_path, local_path, hostname, username, password)
